You need not incorporate both +65 and +90 in the stitch - either should cover the zenith - it's a belt-n-braces approach to shoot both.

The +65 is more likely to enable APP/APG to detect a link between it and the main row of 6, sometimes a +90 will just be blue sky or white ceiling and then APP/APG won't find any feature to match with the main row of 6.

So in such circumstance the +65 may work best, especially if you give some consideration to the direction in which you shoot it to ensure good features fro matching between the +65 and the main row of 6.

It doesn't take long to shoot the few extra 'zenith' and zenith shots.
